Method of manufacturing light emitting device and light emitting device

摘要

A method of manufacturing a light emitting device includes: providing a light emitting device in which a first and second semiconductor laser elements are connected in series; performing a first measurement that includes supplying current to the first semiconductor laser element to measure at least one property of the first semiconductor laser element, and supplying current to the second semiconductor laser element to measure at least one property of the second semiconductor laser element; supplying current to the first and second semiconductor laser elements for a length of time; performing a second measurement that includes supplying current to the first semiconductor laser element to measure the at least one property of the first semiconductor laser element, and supplying current to the second semiconductor laser element to measure the at least one property of the second semiconductor laser element, and evaluating the first and second semiconductor laser elements.
